To: all whom it may concern:

Be it known that I, CLINTON B. KEITH, a citizen of the Unitedv States, residing at West Frankfort, in the county of Franklin and Stateof Illinois, have invented new and useful Improvements in Ice-Shaving. Ma-- chines, of which the followingis a specification.

This. inventionrelates to an ice cutting machine, the general object of the invention being to provide a casingfor containinga block-of ice and receptacles for liquids to. becooled with means for cutting. shavings. or small-pieces: from the block ofice when desired. without removing the block from thecasing.

Another objectof the invention is to provide power means for operating the cutting means and feeding means operatedfrom the power means. for pushing. the block against the cutt-ing meansn A further object of the invention is to provide auxiliary cutting means for breaking up, any large pieces broken from the block.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, .to be hereinafter fully described, illustrated in the accompanying. drawings and specifically pointed out in the appended claims;

In describing my invention in detail, reference. will be had'to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation with parts broken away of the invention.

In these views, 1 indicates a casingswhieh is supportedv from the legs 2. andwhichis, shaped to, receive ablock= of. ice,-v such as;

shown at A, and the liquid containers B, the.

contents of which will get cooledby-theice. The containers B. are provided. with. the. faucets 3 which extendthroughthe;casing: and. with the tops, 4 Whichare clamped tin: position by the nuts 5-. Thecasinggiseproe vided with a cover. 6. which is provided with; a liquid sea], as. shown; at 7. Slats. Sears: p lacedzin the bottom of thecasing andupon. which the block rests sothattheeblock-can. be easily movedin the casing. Anextension;

9 is formed at one-end ofttheecasing andas shaft 10 passes through the extension arid-is connected. with the shaftof motor. 11; sup ported by the hangerv 12..supported.fronrtlie. bottom of thecasing; A gear casing- 13 is; pivoted to. this shaft. and this. casing. rotat+ ably, supports: a vertical. shaft. 14,. which is. geared to the shaft 10. byv the; gears-.15.; shaft 16 is rotatably mountedin the lower? part of the extension 9, and is connected with the shaft 10 outside of the extension by the.

gears 17.. A. crank disc 18 isfastenedto. the shaft 16 and the crank: pinthereof engagesa slot. 19. in an arm-20 which -dependsfr.om. the. casing13, the parts beingso arranged,

that as. the shaft 16 rotates.thepin 18;en.-.

gagingthe slot: 19 will causethe gear. casinggg v and the shaft. 1 1 to oscillate. aswill be: unT derstood. The upper end of theshaftlt-is, guided .in its movement by the guideway; 21; in the upper part of the casing'and said. shaft is provided with the cutters122 which are arranged to engage the end'ofthe-block of ice andthus shavesmalllparticles therefrom as. the shaft oscillates and. rotates.- These particles: will. drop i into the extension". 9 and pass. therefrom through thechute 23: which .is carried by'therslide 24:, operatedbyj. the handle 25. In one position of the-parts the slide Qtwill cover the outlet: opening and. thusprevent discharge of ice: fromth'e: device or the inlet of-air thereinto and-in the: other. position. the chute 23. will be under; the outlet opening. so that the: ice can; pass: therethrough. The. slide is :provided: with .1 a. water sea-1.25 and': issupported vertically by. the pins 26' so that in its closed position it-will be raised to make active-the waterseal. Thehandle is fastened to a SWltChz. 2,7: which controls the circuit to-the. motor 11% so: that when the slide is closed the circuitof the motorwill-be broken. The sha t 16 is provided with the cutters 8 which operate in conjunction with the grate bars 29 placed below the same so that any large particles of ice dropping down the extension will be broken up by these cutters and grate bars. I may use difierent kinds of cutters 22, as shown in Figures 9 and 10, where the cutter 22 is used for shaving the ice, while the cutter 22 is used for cutting small particles about the size of hail from the ice. These cutters are provided with square openings for fitting over the square portion of the shaft.

The means for feeding the block of ice against the cutter comprises a screw shaft 29 placed in the bottom of the casing and en- -gaged by a movable nut member 30 which is attached to a feed plate 31 in the casing and which is designed to engage the rear end of the block of ice. This plate slides on the two guide bars 32 and by lifting up the nut member 30 it will be freed of the shaft so that the push plate can be pulled back to its starting, point without turning the shaft. The shaft can be turned by the hand wheel 33 though I prefer to turn it from the motor through means of a lever 34 pivoted to the extension 9 and having a projection at each revolution of the shaft 16 the lever 38 is rocked topull the dog 41 into engagement with theratchet 4:2 to rotate the same one step and thus turn the shaft 29. This turning movement of the shaft will be communicated to the feed plate 31 by means of the nut 30.

From'the foregoing it will be seen that ice can be shaved from the block or small particles cut therefrom, according to the kind of knives used, and these particles dropping through the extension 9 will be discharged through the chute 23 when the same is in operative position; The cutting action results from the reciprocatory movement of the shaft 14 and the rotary movement thereof. When the cutting action is taking place the ice is fed step by step towards the cutting means and the parts are so timed that the cutting shaft is at oneend of its limit of movement before the feeding action takes place so that the ice block is not contacting with the'cutters when the parts are at rest as the icewill not be fed against the cutters until the cutter bar starts on its return movement. v Itis' thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall with in the scope of the appended claims.

That I claim is 1.
